IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 106,235, dated August 9, 1870.

To all whom it may concern:

Be it known that I, JAMES B. TIBBrTs, of Portland, in the county of Ionia and State of Michigan, have invented a new and useful Improvement in Gultivators; and I do hereby de- Glare that the followingl is afull, clear, and eXactdescription thereof, which will enable others skilled in thc art to make and use the same, reference heilig had tothe accompanying drawings, forming part of this specileation.

Figure l is a side view ot my improved cultivator, partly in section, through the line m x, Fig. 2. Fig. 2 is a top view of the same.

Similar letters of reference indicate correspondingfparts.

My invention has for its object to improve the construction of horse hoes and cultivators, so that the hoes, shovels, or plows may be readily adjusted to turn the soil toward or from the plants, as may be desired; and it consists principally in hinging the hoes, shovels, or plows to the standards, as hereinafter more full y described.

tended upper ends of the standard E, or may` be made separate from said standards, and which are connected by the cross-bar or round I. The draft strain upon the standards E is sustained by the braces J, the forward ends of which are attached to the beam A.

K are the adjustable hoes, shovels, or plows,

i to the middle part of the rear sides of which are attached eyes L, to receive the hooks M, which n t are secured to the standards E by straps, ferrules, or bolts, as may be desired or more convenient. One of the hooks M should be turned up and the other down, to guard against the are pivoted the outer ends of the bars or rods N, the inner ends of which are pivoted to the lower end of the lever O, which passes up through a cross-slot formed in the bar F, which serves as a guide and support to the lower end of the lever O, and which also limits the movement of the said lever. The lever O passes upthrough a slot in the rear part of the beam A, and is pivotedV to said beam, as shown in Fig. 1. The upper end of the lever O projects upward into such a position that it may be conveniently reached and operated by the driver.

through a hole in said lever and through one or the other ot' the holes in the plates or bars I?, attached to the beam A, and which project upward upon the opposite sides of the said vlever O.

2. The combination, with the beam A and standards E, of the hinged plows K, bars or rods N, and pivoted adjustable lever O, all arranged to operate as specified.
